;. V BOBBIN-CLEANEB.

noisyi4;

To all whom it mafl vomem:

Beitknown that I, \VILLIAM Loivzo, a citizen of the United States, residing at Fitchburg, in the county of W'orcester and State of Massachusetts, have invented a new and. useful Bobbin-Gleaner, of which the following is a specification.

"This invention relates -t-oa machine for stripping filling from bobbins.

V substantiallyautom'atic manner; to provide means whereby the filling can be cleaned frombobbins: throughout the entire length thereof and whereby the irregularitiesion the surface of the bobbin'will not interfere with the cleaning operation, and also applicable to bobbins of different sizes; also to provide a construction in which the bobbin holding and stripping devicescan be operated .convenientlyby power if desired, although these parts of the machine are so arranged that they could be operated by turning a shaftby hand and certain results could be secured in that way.

The invention also involves means wherecbylthe bobbin isguided so that thebobbin stripping members willtravel along it in a tunifOrmmanner, and'means for operating "the-parts accurately and effectively.

' gFurtheriobjects and advantages of the invention will appear hereinafter f Reference is to be had to t-he accompanying drawings; in which I Figure l is a front elevation of apower 1 operated machine constructed in accordancewith this invention; Fig. 2 is a plan of a portion thereof;-Fig. 3 is .a sectional eleva-- tion of the supporting member for the machine showing most of the operating connections in side elevation; Fig. 4 is a partial plan view showing the operation of the bobbin holding and cleaning-jaws; Fig. 5 is a-- front elevation on enlarged scale showing how these ja'ws'com'e into operation on the bobbin; Fig. 6 is a similar view showing a later stage in the operation; and Fig. 7 is a side elevation of a portion of the ma- Specification of Letters Patent.

chine showing the guiding means for the bobbin.

In the form of the invention illustrated in the'drawings the machine is shown as i mounted on a bench lOor-other support and as provided with a counter-shaft 11 with tight andloose pulleys 12 for-receiving power. On this shaft 11 is a pulley 13 delivering power to a pulley ,ltonthe main shaft '15 .of the machined. On this shaft'is. located a camil'ifor each machine' yvhich during each rotationv of the 'shaftfpresses down on a metalplate 18 on the 0 5 of 11 member orframe l9 pivoted on a horizontal axis 20. 'This frame is yieldingly held'l'up by a spring 21 orin any'otl ier desired'inanner, and it will be obvious that the 'rotation p 7 of the shaft resnus. in positively lowering it and allowing it to rise by the action of the spring onc'eduring each revolution. On this frame are. pivoted on verticaflaxes a pair of iron levers 22, each ha'ving' asteel. aw 23 thereon. These levers-are held normally'in the position indicated ini Fig. 2 by a pair of springs 24 mounted o'narms 25 on the frame. In. this p osition1stops26 on' the iaws'come into contact with plates 27 fixe such position that they will engage a bobbin,

on the frame and thejaws areheld in but can be inoved outwardly by (contact therewith in opposition to the springs.

The springs 21 and 24 are adjust-ably con-f v nected at their ends with the supportszwhich hold them by means of straps 29 which are provided with a plurality of-pe'rforations at d ifferent distances from their ends for receiving the ends of the springs. l I

Mounted on the shaft are a pair of o ppfo site face cams 30. Each'of these operates cam roller 31. connected with alframe] .132

wliichis'pivoted at 33 on the: supportlt) and is adapted to work bacloandqforth on this pivot. To keep the rolls in contactwith the'cams each frameisshown as provided with a counter-weight 34:.operati-I1g between guides 85 on the base. 7 These frames. are n position to engage the arms of thellevers 22 as indicated in Fig. {l to. open the jawsat predetermined times and allow the bobbin to be removed therefrom and ainew o ne substituted.

In order to keep the proper contact with the jaws during the' oscillating motion of the frame 19, this opened by the cams,

frame is provided with a right angled projection 38 which engages between a pair of rolls 89 on a sliding carriage 40. This carriage slides on rolls 41 mounted on the base 10 and is provided with a cup 42 having a depression in the top for receiving the end of the bobbin. As the frame 19 moves down the carriage 40 moves in so. that the cup is always at the same distance from the projection 38, and the bobbin is always parallel with that projection, that-is, perpendicular to the body of the frame 19.

The operation of the device will be obvious from What has been said heretofore.- The cam 17 forces the frame down and allows it to rise during a part of a revolution, but during more than half of the time the frame preferably is at rest at its uppermost ositlon, so the attendant can replace the b0 bin very easily. While the frame is up at its topmost position the jaws are the bobbin is removed by hand, and a new one substituted, and

,as indicated in Fig. 6, the bottom of the then the frame starts to move downwardly which closes the jaws from the position shown in Fig. 5.- The further downward movement of the frame causes the jaws to engage the filling and push it off the bobbin,

bobbin being moved slightly by the carriage 40 to keep it in proper relationto the jaws.

. .As the framerlses the jaws are held by spring pressure against the bobbin, but do not injure it and they are removed from it automatically by the cams when the frame reaches its upper limit.

Although I have illustrated and described a preferred embodiment of the invention, I am aware'that many modifications can be made therein by any person skilled in the art without departing from the spirit of the invention as expressed in the claims. Therefore, I do not wish to be limited to all the details of construction herein shown and described, but

What I do claim is 1.
